Magnetic disk device and magnetic head slider
View Patent ↗A magnetic disk device includes a magnetic disk, and a magnetic head slider. The slider has a magnetic head, a plurality of surfaces which are formed sequentially from an adjacent side to a magnetic disk, and a slider rail surface which is arranged near an air flow-out edge on a nearest surface of the plurality of surfaces. The slider rail surface includes a long sideways rail surface on an air flow-in side and a lengthwise rail surface on an air flow-out side. The nearest surface of the plurality of surfaces is arranged only in a center area with respect to a width of the slider near the air flow-out edge and has a width substantially less than the width of the slider. An area of the long sideways rail surface is larger than an area of the lengthwise rail surface.
1. A magnetic disk device comprising:
a magnetic disk;
a magnetic head slider having a plurality of surfaces which are formed sequentially from an adjacent side to a magnetic disk, a slider rail surface which is arranged near an air flow-out edge on a nearest surface of the plurality of surfaces, the slider rail surface including a long sideways rail surface on an air flow-in side and a lengthwise rail surface on an air flow-out side, and a magnetic head;
wherein the nearest surface of the plurality of surfaces is arranged only in a center area with respect to a width of the slider near the air flow-out edge and has a width substantially less than the width of the slider; and
wherein an area of the long sideways rail surface is larger than an area of the lengthwise rail surface.
2. A magnetic disk device as claimed in claim 1 , wherein a width of the long sideways rail surface is wider than a width of the lengthwise rail surface.
3. A magnetic disk device comprising:
a magnetic disk;
a magnetic head slider having a step air bearing surface which is arranged only in a center area with respect to a width of the slider near an air flow-out edge on the slider and has a width substantially less than the width of the slider, a slider rail surface which is arranged near the air flow-out edge on the step air bearing surface includes a long sideways rail surface on an air flow-in side and a lengthwise rail surface on an air flow-out side, and a magnetic head; and
wherein an area of the long sideways rail surface is larger than an area of the lengthwise rail surface.
4. A magnetic head slider according to claim 3 , wherein a width of the long sideways rail surface is wider than a width of the lengthwise rail surface.
5. A magnetic disk device comprising:
a magnetic disk; and
a magnetic head slider having a step air bearing surface which is arranged only in a center area with respect to a width of the slider near an air flow-out edge on the slider and having a width substantially less than the width of the slider, a slider rail surface which is arranged near the air flow-out edge on the step air bearing surface, and a member which is arranged between the slider rail surface and the air flow-out edge;
wherein an area of the slider rail surface is larger than an area of the member.
6. A magnetic head slider according to claim 5 , wherein a height of the slider rail surface from the step air bearing surface is different from a height of the member from the step air bearing surface.
7. A magnetic head slider according to claim 5 , wherein the slider rail surface is separate from the member.
8. A magnetic head slider according to claim 5 , wherein a width of the slider rail surface is wider than a width of the member.
9. A magnetic head slider according to claim 5 , wherein the member is another slider rail surface.
10. A magnetic head slider according to claim 5 , wherein the member includes a contact pad.
